Abstract: In a stream computing application shutdown, a shutdown message is received by a source operator of the stream computing application. In response, the source operator stops acquiring data from external sources, sends any cached data to an output queue of the source operator, sends the shutdown message to the output queue of the source operator, and sends the cached data and shutdown message to an input queue of another operator in the stream computing application. The source operator then terminates. In response to receiving the shutdown message, the other operator completes the processing of data in its input queue and sends any outputs from the processing of the data in its input queue to one or more output destinations. The other operator then terminates. In this manner, a stream computing application may be shut down while ensuring that any already inputted data is processed to completion, thus avoiding data loss.

Abstract: A method, system and computer program product for managed object replication and delivery redirects, directly or indirectly, a client's request for an object that is not available at a best or optimal handling edge server of a network to a parent server that has the requested object. So, where the requested object is not available at the handling edge server, the client's request is redirected directly to the parent server that can provide the requested object to the client or indirectly via one or more parent servers to a parent server that can provide the requested object to the client. The method, system and computer program product further intelligently replicates the object to the edge server if the object is popular enough. Likewise, an object is removed from an edge server when it is no longer popular. All redirection and replication operations are preferably transparent to the end-user and do not degrade the quality of service.

Abstract: A first party, such as a residential subscriber to an Internet Service Provider (ISP), logically partitions its computing resources into an end user partition and a crowd sourced cloud partition. The first party installs a crowd sourced cloud application in each cloud partition. Together, a cloud provider computing system and each cloud application orchestrate cloud services over a communications network, such as the Internet. For each crowd sourced cloud application, orchestration involves registering cloud services with the cloud provider, provisioning each registered cloud service that is requested by the cloud provider, and operating each provisioned service. For the cloud provider, orchestration involves publishing each registered service as available to crowd sourced cloud users, receiving requests for cloud services from a crowd sourced cloud user, and requesting, from a crowd sourced cloud application, a registered service responsive to the request for cloud services.

Abstract: For distributed processing using forecasted location-based IoT device clusters, at a central IoT device, a data source that is to be used and a duration for processing a workload is determined. A set of IoT devices operating within a threshold distance from the data source at a first time is selected. A first subset of the IoT devices is selected to form a cluster of IoT devices where each IoT device satisfies a clustering condition. A second subset of the first subset is selected to form a sub-cluster of IoT devices where a forecasted travel path of a member IoT device in the second subset keeps the member within the threshold distance from the data source for the duration. A lightweight application is configured at a first IoT device in the second subset which enables the first IoT device to participate in the sub-cluster and process the workload.

Abstract: A domain name dependency server (DDS) stores known relationships between domain names. In response to a domain relationship query from a local DNS server for a given domain name, the DDS supplies the domain names that are related to the given domain name. This reduces or eliminates serial requests for the related domain names from the local DNS server, reducing overall DNS lookup latency for the requested service. The DDS can be shared among multiple local DNS servers, and can be updated dynamically or manually to enhance the accuracy of its stored domain name relationships.

Abstract: Systems and methods described herein provide redundant functionality for multi-cloud high availability continuous service provisioning. Service rule configuration of regional internet services platforms at different geographical locations are provisioned through a multi-cloud provisioning platform. The systems and methods provide that there is no disruption of service provisioning, in the event of a failure of one cloud provisioning platform, as long as at least one other cloud provisioning platform is available. In the event of a cloud disaster outage at one cloud provisioning platform, a regional internet services platform will automatically register with another active cloud provisioning platform.

Abstract: Generally in a computing environment, executing work based on time (i.e. according to a predetermined schedule) is a common need. However, in cloud based systems, scheduled work may be expensive to customers as generally customers rent system resources. Thus, having a processor dedicated to performing actions that have been pre-scheduled can be expensive. This application describes using a continuation-based runtime for scheduling time-bound and/or periodic work in a distributed (i.e. cloud) system. A system architecture and computer-implemented method are described that deploy an environment-independent action to a remote-based system (such as a cloud computing system, for example). The action is limited to using a predetermined amount of resources and is limited to simple, non-cpu intensive orchestrations of network calls.

Abstract: Systems and methods are described to enable assessment of demand for points of presence (POPs) within a content delivery system, independent of the capacity of such POPs. The content delivery system can utilize load balancing technology to distribute user requests for content to various POPs, based at least partly on the capacity of the POPs. Because load balancing generally occurs prior to a user's connection to a POP, the monitored load of individual POPs may not accurately reflect user demand for the individual POPs services. Accordingly, systems and methods are disclosed to correlate pre-load-balancing requests, such as DNS requests, with post-load-balancing demand levels. Thereafter, the determined correlation can be utilized to assess user demand for individual POPs, independent of the observed load on that individual POP. In some instances, POPs or other network components can be clustered to determine capacity-independent demand for a collection of POPs.

Then, the wireless access point may transmit a request message to a service server with user identification information of the user equipment and the assigned IP address. In response to the request message, the wireless access point may receive predetermined multimedia contents and deliver the received predetermined multimedia contents to the user equipment based on the assigned IP address.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for aggregating requests for resources. In one aspect, a method includes receiving a set of requests for computing resources. Each request specifies one or more computing resources and, for each of the one or more computing resources, a quantity of the computing resource requested. A quantity-based provider condition that a request must meet for inclusion in an allocation process is identified. Each received request that fails to meet the quantity-based provider condition is included in a proper subset. Requests in the proper subset of requests are grouped into one or more groups based at least on the quantity of the one or more resources specified by each request of the proper subset and the quantity-based provider condition. A respective combined request is generated for each group of requests.
